Serving others is hard

I can't believe how hard it is to honestly serve another person completely, with no thought of myself.  I am embarrassed at my inability to do this at all. I completely want to do things for others on my time, in my way, and certainly want to be sure it is noticed. If anything comes in the way of that, then look out, my attitude really changes. I hate that this is true about myself and I want to be different. I know it's not possible to muster up a new attitude, but then again those are the fruits of true faith. I have to believe and trust who I am in Christ and not what I do, have done, or will do. I also am free in that position to love others more with no need to prove myself through my works. I am blown away to think of Jesus Christ, living an entire life of service with no hint of selfishness, irritation or annoyance at the needs and requests of others.
